MAXIMILIAN CHARLES SOHWEINERT, OF WEST HOBOKEN, NEW'JERSEY, AND HENRY P.KRAFT, OFNEW YORK, N. Y.

WATER-B O'ITLE STOPPER.

To all whom it "may concern:

Be it known that we, Mnxnunnm Ormnnns Sonwnr- NERT, residing in WestHoboken, in the county of Hudson and State of New Jersey, and HENRY P.KRAFT, residing in the borough of Brooklyn, in the county of Kings, cityand State of New York, citizens of the United States, have inventedcertain new and useful Improvements in Water-Bottle Stoppers, of whichthe following is a specification.

This invention relates to water bottle stoppers and aims to providecertain improvements therein. Stoppers of this kind as heretoforeconstructed have usually consisted of a socket member and a stopperproper which is adapted to screw into or upon the socket member, asuitable packing being carried by the one or other of said parts to forma leak-tight joint between the two. In the best devices of this kind thestopper proper is formed of two pieces of sheet metal, the lower ofwhich is drawn to cup shape and is provided at its upper end with anoutwardly extending lateral flange, and the upper of which is formed asa cap or disk, the edge of which is crimped or bent over the flange ofthe lower member so as to make a tight joint between the two. Thisconstruction while providing a strong. and durable stopper, has thedisadvantage of forming a flange at the top of the stopper which is ofconsiderably greater diameter than the body thereof. This renders theuse of such stopper difficult in certain forms of water bottle stopperswherein the stopper proper is designed to screw below the top of thesocket member. In this and other types of stoppers the packing materialis formed as a disk which is carried on the under face of the stopperproper, the socket member being formed with a seat against which saiddisk contacts when the stopper is screwed home. Such packing is liableto distortion as it is pressed between the two metal surfaces and thisresults in the necessity of frequently renewing the packing in use.

Our present invention obviates these several disadvantages and providesa stopper which is of the same general diameter throughout, and which,while carrying the packing disk on its under face as before, providesmeans whereby distortion of the packing is prevented. The stopperprovided by our invention is also of cheap and durable construction.

In the drawings wherein we have illustrated several embodiments of ourinvention, Figure 1 is a central vertical section of a hot water bottleprovided with a stopper made in accordance with our invention; Fig. 2 isa side elevation of the stopper proper removed; Figv 3 is an enlargedfragmentary section of a portion of the stopper shown in Figs. 1 and 2;Fig. 4 is a central section of a modified form; Fig. 5 is a view similarto Fig, 3 showing a portion of Fig. 4; Fig. 6 is a Specification ofLetters Patent.

central section of a further modification; Fig. 7 is a view similar toFig. 3 showing a portion of Fig. 6.

Referring to the drawings, let A indicate any suitable form of hot waterbottle having a neck a and a funnel b. The socket member B is vulcanizedor otherwise secured to the neck a and is formed with an inwardly turnedflange 0 constitutinga seat for the stopper proper when the latter isscrewed downi The stopper C is formed with a body portion (1 and ahandle e of any suitable construction, that shown being formed of a wirebent to-proper shape with its ends riveted to the upper portion of thebody (Z.

Our invention is particularly directed to the construction of the body(Z. At present it is customary to form such body (Z of two sheet metalmembers, the lower of which is cup-shaped with its open side uppermost,such member being provided with a flange which extends outwardly to aconsiderable distance beyond the side wall of the cup. The upper memberis usually formed as a cap or disk of sufiicient diameter to extendbeyond the flange of the lower member so that its edge may be crimped orbent under such flange to unite the parts. This construction involves aconsiderable increase in diameter of the stopper at its upper end, sothat it is not adapted for use in water bottles in which the stopperproper is designed to screw inwardly beyond the upper edge of the socketmember. Such construction also necessarily leaves a somewhat imperfectjoint at the top of the stopper, which is difficult to nickel plate.

According to our invention we provide a construction in which the bodyof the stopper is formed in two parts as before, but in which such partsare so united that the stopper, at their point of connection, shall haveno greater diameter than that of its threaded portion, whereby thestopper may screw into the socket member past the end thereof. One formof such connection is made in the manner shown in Figs. 1 to 3 of thedrawings, wherein the body 11 of the stopper is constructed of sheetmetal and is formed with a cup-shaped upper section 9 and a disk shapedlower section h, the edge of the disk It being bent inwardly to form ashoulder y to prevent relative movement of the section 9 in onedirection, and then outwardly to form a flange 1' to prevent suchmovement in the opposite direction. The edge of the cup 9 is bentinwardly in this construction to form a flange j which lies between theshoulder y and the flange 1'. In process of construction the disk h isfirst formed and the flange j of the section 9 is then turned into thegroove formed between the flange i and the shoulder y of the diskPreferably the parts are arranged in the manner shown, that is to say,with the cup 9 forming the upper part of the body of the stopper and thedisk It forming its lower part. When so constructed the handle 0 isiastened directly to the threaded portion of the body, so that thestrains in use are transmitted to the body through its integral topwall. It the position of the parts is reversed and the handle a fixed tothe disk h or its equivalent, the strains of use would be transmittedthroughthe flanged joint between the parts, and such joint would hencehave to be of strong and rigid construction. This is not necessary whenthe parts are constructed as shown. On the contrary we prefer ordinarilyto provide a loose connection between the disk and cup so that the diskshall be free to rotate inde pendently oi the cup, this constructionbeing shown in Figs. 1 to 5. In stoppers of this ype the packing washeris usually formed as a disk is which is carried at the bottom of thestopper, being fixed thereto by a rivet Z. In previous constructions,when the stopper has been screwed down, the packing washer has beenliable to distortion between the rigid under face of the stopper and theseat 0. By our present invention we prevent such distortion by swivelingthe packing disk It to the part 9 oi the stopper body in the manner justdescribed so that the packing is pressed down upon the seat 0 withoutrotation. In this construction the disk acts in eflect as anantiiriction member between the packing and the cup 9, permitting thelatter to rotate without turning the disk.

The stopper provided by our invention is especially adapted for use inconnection with the particular type of socket member shown in Fig. I. Inthis construction the socket member is extended upwardly a considerabledistance beyond the neck a oi the bottle and is provided with ports oropenings in. through which the bottle may be filled or emptied. Duringthis operation the stopper proper is screwed upwardly to the positionshown. in Fig. 1 so as to uncover the ports m. This constructionnecessitates that the stopper proper be screwed downwardly aconsiderable distance below the top ol' the socket member in order toclose the bottle. The formation of the stopper body without a projectingflange permits this action without increasing the length of the stopper.

In Figs. 4 and 5 we have shown a mode of attachment which differssomewhat from that shown. in Fig. I. In these figures the flanges arereversed so that the shoulder y and flange i are formed upon thecnpshaped portion g while the flange j is formed on the disk h. In thisconstruction the flange j is crowded into the space between the flange iand the body of the portion g.

In Figs. 6 and '7 we have illustrated a connection similar to that ofFig. l, but having the flanges pressed tightly together so as to preventrotative motion ol' the disk h with relation to the portion 5 Othermodifications may be made without departing from the spirit of ourinvention. For instance it is not essential that the joint between theparts be made at the lower part of the stopper, or that the stopperconsist of two portions only. Neither is it necessary that theparticular form oi inter-locking flanged joint be used, as any similarmeans ior connecting the parts may be employed. Other modifications mayalso be made.
